Abstract

En akustisk hørselsanordning er presentert, omfattende et skum og minst en kom- ponent som er mekanisk forbundet med skummet. Den mekaniske forbindelsen av komponenten oppstår under fremstillingen, hvori komponenten plasseres inn i et hulrom i en støpeform som en innsats og et skum dannes inne i støpeformen for å tillate kontrollert penetrasjon av komponenten under skumming, l et utførel- seseksempel, omfatter den minst ene komponenten en stamme med en tupp ved en ende, hvori tuppen omfatter minst en åpning som i det minste er delvis gjen- nomgående. Den mekaniske forbindelsen er resultatet når skummet strekker seg gjennom den minst ene åpningen.
